在 SQL Server 2005 和 2008 上启用 TCP 的注册表设置是什么? [英] what are registry settings to enable TCP on SQL Server 2005 and 2008?

问题描述

我想以编程方式在 SQL Server 上启用 TCP 连接.我相信我们可以通过修改注册表项并重新启动 SQL Server 服务来实现这一点.我应该编辑哪个注册表?

I want to programatically enable TCP connections on SQL Server. I believe we can achieve this by modifying registry entries and restarting SQL Server service. What registry should I edit?

推荐答案

除非你有充分的理由直接修改注册表，否则我建议你考虑使用 WMI.WMI 将为您提供更多版本不可知的实现.可以通过 System.Management 命名空间访问 WMI.你可以有类似这样的代码.

Unless you have a good reason for modifying the registry directly, I suggest you consider using WMI. WMI will provide you with a more version agnostic implementation. WMI can be accessed through the System.Management namespace. You could have code that looks something like this.

public void EnableSqlServerTcp(string serverName, string instanceName)
{
    ManagementScope scope =
            new ManagementScope(@"\\" + serverName +
                                @"\root\Microsoft\SqlServer\ComputerManagement");
    ManagementClass sqlService =
            new ManagementClass(scope,
                                new ManagementPath("SqlService"), null);
    ManagementClass serverProtocol =
            new ManagementClass(scope,
                                new ManagementPath("ServerNetworkProtocol"), null);

    sqlService.Get();
    serverProtocol.Get();

    foreach (ManagementObject prot in serverProtocol.GetInstances())
    {
        prot.Get();
        if ((string)prot.GetPropertyValue("ProtocolName") == "Tcp" &&
            (string)prot.GetPropertyValue("InstanceName") == instanceName)
        {
            prot.InvokeMethod("SetEnable", null);
        }
    }

    uint sqlServerService = 1;
    uint sqlServiceStopped = 1;
    foreach (ManagementObject instance in sqlService.GetInstances())
    {
        if ((uint)instance.GetPropertyValue("SqlServiceType") == sqlServerService &&
            (string)instance.GetPropertyValue("ServiceName") == instanceName)
        {
            instance.Get();
            if ((uint)instance.GetPropertyValue("State") != sqlServiceStopped)
            {
                instance.InvokeMethod("StopService", null);
            }
            instance.InvokeMethod("StartService", null);
        }
    }
}

此代码假定项目引用了 System.Management.dll 和以下 using 语句:

This code assumes a project reference to System.Management.dll and the following using statement:

using System.Management;

Sql 协议 博客有一个 文章，其中详细介绍了上述代码的作用.

The Sql Protocols blog has an article that goes into some detail as to what the above code is doing.

注意:如果防火墙阻止了端口，您仍然无法通过 TCP 访问服务器.

Note: If a firewall is blocking the port(s) you will still be unable to access the server via TCP.
